We are working on Xilinx MPSOC which has 4 A53 cores, We are trying to run Linux(EL1) on 3 cores and Freertos(EL3) on 4th core. When software generated interrupts are raised from Linux , Freertos is not getting any interrupts. How to make interrupts work between Linux and Freertos when the cores are running at different ELs.

Yes it works without any problem on zynq7000, but on ultrascale, linux runs on EL1 mode and freertos on EL3 mode. So from Linux when I send SGI, it is not generating any interrupt on freertos that is running on another core with EL3 mode. Please suggest if i need to configure it using ATF or on Freertos itself as it is running with full priveliges.
